My amp is a Cary Rocket-88, which I probably plan on keeping they put me in my grave or it stops working, whichever comes first.

I don't need multiple inputs, or outputs ... all I basically need is volume attenuation. But, there is a catch - the Cary has an unusually high input voltage. It needs a lot of gain to be driven properly.

I understand that the CSP3 has gain attenuators, but the rather large price jump in the current model keeps me from jumping on that, and it has features (that I will pay a lot for) that I will never use.

Would the ZBox or ZStage be up to the task of being the very simple preamp that I am looking for?
